The College of Agriculture discussed a master's thesis on the physiological effect and reproductive efficiency of local Awassi ewes dosed with a solution of spirulina algae and folic acid until the end of the early pregnancy stage in the summer months, by the student Alan Sardar Abdul Karim, and supervised by Assistant Professor Dr. Sarmed Abdul Razzaq Aboud Al-Saadi.
Due to the lack of research and studies in the field of testing the physiological effectiveness of spirulina algae and folic acid in causing noticeable changes in productive traits, growth indicators, biochemical standards and early pregnancy in ewes, the current study aimed to focus on this important and vital physiological stage of the stages of breeding and production and study the effects of the studied treatments in local Awassi ewes.
The study concluded that dosing pregnant ewes with the aqueous extract of spirulina algae with or without folic acid led to an increase in the final weight rates of ewes and the total weight gain, which gave a positive indication of the improvement of their growth index. It was found that treating ewes with the aqueous extract of spirulina algae with or without folic acid led to an increase in the rates of estrus, the number of twins, and the total number of fetuses, and regulating vital physiological indicators in the early pregnancy stage such as the ewes' temperatures, breathing rate, and pulse effectively, which gives a tangible indication of the anti-stress effect during the twin pregnancy of ewes. The study treatments also contributed to improving many biochemical characteristics in pregnant ewes.
